Air Purifier Filters And Their Types

Most of the air purifier filters that you find in stores are the ones that consist of a sheet of fiberglass strands within the filter. These shards and particles are randomly shot into the wide frame of the filter, and then in turn when sold, the filter is placed in an air purifier. You may be wondering how can something like that keep out anything with any sort of efficiency. It is sort of a coincidence, but not quite.

The fiberglass that is used to fill these filters is packed very tightly and forced to fit into the small space of the filter, then held together by a wire. Because they are placed so closely together they act as a a barrier against anything 0.2 micrometers to 0.7 micrometers, depending on the grade of the purifier filter. You can find higher grade air purifier filters that can protect against airborne particles that are 0.1 micrometers, which will give you the best protection possible against airborne particles.

The highest grade of commercial and residential filter is HEPA, which is the best type of filter you can get. Though their industrial or medical strength models are used in places that need absolute sterilization, residential HEPA filters are the best filtration you can get in a home. These filters are 99.97% effective against incoming particles and allergens. Any filters that say they are HEPA-type or 95 percent HEPA are not truly what they say they are: filters that only say they are HEPA are high quality.

If you have an electrostatic purifier, then obviously you need electrostatic air purifier filters. These work by charging airborne particles and attracting them to the system’s internal metal plates. These kinds of filters are are second only to HEPA fiberglass filters, and in the long run they can be more affordable. Instead of replacing electrostatic filter models, all you need to do is give them a good scrub down, then they are back to full effectiveness. If you are planning to use your air purifier for at least another few years, investing in an electrostatic model will be cheaper in the long run, even if they are more expensive at the start.

Filters that are not high quality or are poorly made are not good enough to truly protect you from the particles that could be coming into your home, which is what purifiers are supposed to do. If you are worried about your respiratory health, you should spend that little bit of extra money on a filter that is going to actually help you breathe better, rather than one that is cheap and will not do much. You shouldn’t have to put your wallet before your health, and purchasing a high quality air purifier filter with ensure that you stay healthy and make sure that you are safe from anything that could possibly be harmful.

You need to be picky about the air purifier filters you purchase. Filters that are cheap will not protect you from much, but those that are HEPA or other high grade air purifier filters will help you breathe better and keep you safe.
